Warning lights

First off, mine is a 2016 SR5. Only has 33k miles.
Just today, my check engine light, my 4 lo was flashing and my " trak off " lights became active, any thoughts....help!

 

Read the code that's setting off the CEL. It's normal for the Trac Off light to come on with it.

 

I forgot to mention that my shifter had suddenly started feeling gummy. Not moving smoothly.
Took it to Toyota this morning. They just called and said the warning lights are on because of the shifter mechanism and they ordered the part they need. Sure am glad I insisted on the Platinum warranty when I bought it used last October, because the part is about $900.00, which will be covered after my $50.00 deductable. They said it will be ready tomorrow. I hope to learn more about what exactly was wrong when I pick it up.
